jolt/staggering? in head

Idk how to explain this but....here lately I often get this feeling in my head like a jolt or buzz or staggering sensation that only lasts for a split second, then its gone ( I tend to associate it w a jolt of electricity). But these are happening more frequenlty now. There is no pain associated but I have like this numb and tingling sensation on my tongue. Sound familiar to anyone out there??

Welcome to the board. You can see the menu for boards at this site that deal with different topics in the upper left hand corner.

I think I know what you are talking about. Used to happen to me when I
was a teen. I always felt it in the back of my neck. Used to wonder if
a blood vessel had exploded. Anyway, this strange symptom went away
when I was in my 20s.

Hasn't happened for decades. And then it happened again a couple weeks
ago. I never discussed this w/ a doctor. If you find out anything, let
us know. So far as my experience goes, no problems; just a weird sensation.
